Here is a listing of the number of points per game per team for the NFL since 1922: http://www.pro-football-reference.co...FL/scoring.htm

It seems like the high water mark for the NFL is about 46 points per game which is where they are at now and where the CFL has dropped to this season. However, if you look at the CFL since the early 1980s, the league tends to be in the low to mid 50s more often than not in points per game which means that we usually see the equivalent of a TD per game more in the CFL than the NFL. I suspect that this year is a blip for the CFL and that we will see scoring return to somewhat more normal levels over the next year or two.
